One more thing, Cerenia can sting when injected. The pills are usually given if there is no vomiting and kitty can take oral meds. Usual dose is 1/4 of a 24mg pill. If an injection is necessary, I'm giving it every day now by injection, technique helps: keep the Cerenia chilled, and chill the syringe for ten minutes after it is filled, to bring down the temperature. I inject it into the subq fluid bubble or put it in the subq port on the fluid bag and they don't feel it at all.
Adequan is really good stuff, as well. One vet told me to inject it IM, but a second vet told me it can be injected subq. You would do the loading dose once a week for several weeks, then expand to once a month. There is a manufacturers' shortage right now. I have not been able to get any and I think that will continue through August. But I think there is some available with a short date of October 2016. But, a two vial box can last for two years because the dose is so small, so I am holding out, hoping to get some when they release the new batch.
I'm trying to think of safe remedies that address global inflammation. The first thing that comes to mind is Omega 3 oils. In that category, the safest and purest one designed for cats is Nordic Naturals (version for small dogs and cats on the label). You can buy it on Amazon for about $20. Oils are subject to rancidity, and you have to buy ones titrated for a small animal so that they do not get a case of the poops. People strength capsules are generally too strong. Mercola also has a good oil in an airless pump, but their stuff is more pricey. Start with just 4 drops of the Nordic version per meal and increase slowly to the dose on the bottle, or keep the dose low and see if that helps at all. Keep it in the fridge after it is opened.
If I can think of any other remedies, I'll post the info.
All my best,
Bliss
